The engine I purchased online (350 sbc) has a mechanical 4 degree advance (in the timing chain) which I verified manually.
So, next step is to do the timing and I need some assistance.
For a stock chevy engine advance is 6 degrees, so, for this engine do I:
1. add the 6 degrees to the mechanical 4 degrees for a total of 10 degrees.
2. put it at 2 degrees with the thought being that it is 4 degrees below zero (retard) so plus 6 is 2 degrees
3. other thoughts are appreciated.
